## Signed commits

Every commit that reaches the default branch must be signed; a ruleset refuses
unsigned pushes. Estate policy:
[SIGNING-POLICY](https://github.com/hyperpolymath/standards/blob/main/docs/SIGNING-POLICY.adoc).

- **People and interactive agents** sign with an SSH key registered on GitHub
as a *signing* key (`gpg.format=ssh`, `user.signingkey=<key>.pub`,
`commit.gpgsign=true`). The committer email must be verified on that account.

Align the threat model with the SSH signing guidance.

docs/architecture/THREAT-MODEL.adoc, Lines 79-85, still says “Require GPG-signed commits”. This section directs people and interactive agents to use SSH signing keys, as does the linked estate policy. Update the threat-model mitigation to require verified signatures without prescribing GPG, or state the supported signing formats. (github.com)

Review comment at @.github/CONTRIBUTING.md around lines 129 - 131:
Update the threat-model mitigation associated with “Require GPG-signed commits”
to require verified commit signatures without prescribing GPG, consistent with
the SSH signing guidance and linked signing policy.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

- **Apps, bots and workflows** never `git push` local commits. They write
through the API (`createCommitOnBranch` or the estate `signed-push` action)
so that GitHub signs each commit.
- Merge PRs with **squash**. The ruleset checks every commit on the PR branch,
not just the result, so one unsigned commit blocks the merge. Re-create such a
branch with signed commits (`git cherry-pick -S`) and open a new PR.
Rebase-merge replays commits unsigned and is disabled.
